I do think Tesla´s position is very similar to Ford´s position over a hundred years ago. Ford initially had all the same advantages with the T model. Yet Ford was overtaken in the 1920´s by GM who started segmenting the market, giving customers different brands, models and options to choose from.
For the coming years no manufacturer will be able to really compete with Tesla, but I do think Tesla will need to introduce more models and start covering more niches in the car market.
